FiveM license key (sv_licenseKey): where to find it and how to enter it
FiveM2 min readUpdated Oct 19, 2026
Every FiveM server needs a license key from Cfx.re. Without one the server refuses to start. Creating a key is free; this guide shows how to create it and where to enter it.
Generate a Key at Cfx.re
- Log in with your CFX account on https://portal.cfx.re/login.
- In the top menu, click Servers.
- Press the GENERATE KEY button.
- Enter a name and press GENERATE.
- Under Actions, click Copy registration key.
Game Server: Enter the Key in the Panel
- In the game panel, open your server and click server.cfg Editor under GAME SERVER.
- Scroll to the License & API keys section and paste the key into the FiveM license key field. Use Show / Hide to verify it.
- Press Save changes and restart your server from the Console page.
VPS or Dedicated Server
If you run FiveM on a VPS or dedicated server instead, put the key in your server.cfg yourself:
set sv_licenseKey "xxxxxxxxx"
Finished
When the console prints
Server license key authentication succeeded. Welcome!everything is OK. Keep in mind a key is bound to one server at a time; reusing it elsewhere causes server list problems. Brand new server? Continue with where to start.
Common license key errors
Server license key authentication failedorinvalid license key: the key was copied with spaces or quotes missing, or it was generated for another server IP. Open the Cfx.re portal, check the key's details and copy it again; the value must be on one line insv_licenseKey "...".This key is already in useor the server appears and disappears in the list: the same key runs on two servers. Generate a second key; keys are free and you can have several.- Key tied to the wrong IP: in the Cfx.re portal a key can be bound to a server IP. After moving to a new host, edit the key and clear or update the IP, or generate a new one.
- Key from a reseller or a "cracked" package: these are shared keys and get your server delisted. Always generate your own key at portal.cfx.re.
- Keymaster: older guides refer to keymaster.fivem.net; that site now redirects to the Cfx.re portal, where the same keys live under Servers.
